Moisture Control System in Mustard Plants Using the PID Method

Irrigating paddy fields is a very important process for plant growth. When the of irrigating rice carried out by means continuously flowing water and soil moisture value only based on estimates, there are many possibilities not to be measured where this causes plants take long time grow will rot or fail harvest if humidity too high. So final project was designed with title Humidity Control System in Mustard Plants Using PID Method. The way system works placing 5 sensors at five different points read values ​​and each sensor connected Arduino Mega 2560 microcontroller. controller used irrigation Proportional Integral Derivative (PID) get according needs plant. design construction an automatic study successfully using method, corresponding Kp parameter ​​for were obtained, namely = 4.328, Ki 2.634, Kd 3.217. This can reach point mustard plant, which 60% steady state error 0.387% rise 79 seconds. test 7 days comparing average height manual watering area area. growth has difference 1.2 cm. Because focuses also need other nutrients besides water.
